Another list of Trouble Codes... P1443, P0136, P0141 P1131

Il apologize now for making this thread because Im sure there is already one out there for these issues. But My 96 GT is currently acting up, it has a real rough idle and its nice lob is gone. I also have a noticeable loss in power. p01443, p0136, p0141, and p1131 are the current codes I have, Ive seen many other people with these issues but Ive yet to see anyone put an exact finger on everything. Please help...

IMO, you are not likely to find a definitive list for your problem as there are 100's a possible causes.

The P01443 is not a valid DTC code (too many digits).

The P0136/P0141 may indicate a wiring problem to both rear O2 sensors. Any recent exhaust work? Consider looking for burnt wires touching the exhaust pipe. I'm assuming this is a new code and not simply the results of removing the cats.

For the P1131, the odds favor a vacuum leak or exhaust leak. For an exhaust leak, look on the right side.

>>
P0141 - HO2S Sensor Circuit Malfunction (HO2S-12)

P0136 - HO2S Sensor Circuit Malfunction (HO2S-12)

P1131 - Lack of HO2S-11 Switch, Sensor Indicates Lean
Electrical:
Short to VPWR in harness or HO2S
Water in harness connector
Open/Shorted HO2S circuit
Corrosion or poor mating terminals and wiring
Damaged HO2S
Damaged PCM
Fuel System:
Excessive fuel pressure
Leaking/contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system
Induction System:
Air leaks after the MAF
Vacuum Leaks
PCV system
Improperly seated engine oil dipstick
EGR System:
Leaking gasket
Stuck EGR valve
Leaking diaphragm or EVR
Base Engine:
Oil overfill
Cam timing
Cylinder compression
Exhaust leaks before or near the HO2S(s)

The P01443 is a typo lol. P1443 is the correct code I pulled.
